Frequently Asked Questions

What are the wood burner rules in Otago?

Otago has two air zones with different rules. Air Zone 1 (Alexandra, Arrowtown, Clyde, Cromwell) has NZ's strictest limit at 0.7 g/kg — only ultra-low emission burners are permitted. Air Zone 2 (Dunedin, Mosgiel, Queenstown, Wanaka) follows the 1.5 g/kg standard.

What is Otago Air Zone 1 and why is it so strict?

Air Zone 1 covers Central Otago towns (Alexandra, Arrowtown, Clyde, Cromwell) that experience NZ's coldest temperatures and severe winter inversions. Smoke gets trapped at ground level, creating hazardous pollution. The 0.7 g/kg limit and ULEB requirement aim to reduce this.

What subsidies are available in Otago for wood burner replacement?

ORC offers subsidies up to $3,000 for replacing non-compliant burners in Air Zone 1 (Central Otago). Check eligibility with the Otago Regional Council. This helps offset the cost of upgrading to an ultra-low emission burner.

How much does a chimney sweep cost in Otago?

Costs vary by location: $110–$170 in Dunedin and Oamaru, $120–$180 in Central Otago, and $130–$200 in Queenstown and Wanaka. Resort towns and remote areas tend to be more expensive.

How often should I sweep my chimney in Otago?

At least once a year, and twice yearly in Central Otago and Queenstown where extreme cold drives heavy usage. Households burning more than 5 cubic metres of firewood per season should consider a mid-winter sweep.
